NEW YORK (AP) — The last supermoon of the year will light up our December skies soon. A supermoon occurs when the full moon is closer to Earth in its orbit, making it appear up to 14% larger and 30% brighter than a typical full moon, according to NASA.
We can expect to see supermoons multiple times a year, trending in groups due to the moon’s elliptical orbit. This December, we will witness the last of three supermoons in 2025.
You don’t need any special tools to see the supermoon—just a clear night. However, it can be tricky to spot the difference with just your eyes. Interestingly, the moon often looks bigger when it’s close to the horizon, a phenomenon called the moon illusion. This curious optical effect puzzles scientists even today.
William Alston, an astronomer from the University of Hertfordshire, explains, “When you have a supermoon, that effect is just slightly more striking.” Though tides can rise a bit during a supermoon due to its proximity to Earth, the change is subtle and often not noticeable.
In recent years, supermoons have gained popularity on social media, with hashtags like #Supermoon trending. Photos shared online capture the awe of this lunar spectacle, sparking conversations about its beauty and significance.
For those wanting a deeper dive, studies show that lunar events can impact sleep patterns and moods. A study published by the journal “Current Biology” found that people sleep less during full moons, which could be an interesting angle for night owls to consider when planning their outings during supermoons.
As you prepare to gaze at December’s supermoon, remember that it’s not just a pretty sight; it’s a reminder of the fascinating dynamics of our solar system.
